When Y is 2 Z may be -NHNH-, -(NHCm H2m)xNH-, -NHCnH2nNH-. <FORM:0957277/C2/2> where m, n and x are integers.  The compounds of the invention are prepared by reacting a compound: <FORM:0957277/C2/3> with a compound ZHy, and if desired reacting the product with an acid to produce an acid addition salt. Suitable compounds ZHy include ammonia, aliphatic, alicyclic, and heterocyclic mono- and polyamines, guanidine, hydrazine and alkyl or aralkyl hydrazines.  Many such compounds are specified.  Suitable starting materials are prepared by chlorinating a -picoline or partially chlorinated 2-trichloromethyl-pyridines.

Title: Improved process for the production of extensible contractile tubular, annular or the like film products, for example, caps or rings for stoppering bottles
IPC: B29D99/00
Filed: 1947-03-06
Abstract: A process for the production of extensible contractile tubular annular or the like film-products, for example, caps or rings for stoppering bottles, having a base consisting of cellulose triacetate, comprises forming such products by a wet process from a solution of cellulose triacetate in a mixture consisting of glycol formal and a small proportion of water, and coagulating the shaped products with a mixture consisting of glycol formal and a large proportion of water. Preferably the glycol formal is used in association with plasticizers, e.g. triacetin or glycol diacetate.  The maximum glycol formal content of the coagulating bath is about 15 per cent.  An aqueous solution of glycol diacetate may be used as an after-treatment.  In example 1 cellulose triacetate is dissolved at 40-50 DEG  C. in a mixture of glycol formal with a little water, methyl glycol phthalate and " Plastomoll " (Registered Trade Mark), dye stuffs, fillers and the like being added, if required.  Formers are dipped into this solution, drained off, and immersed at 20 DEG C., in a coagulating bath of a 14 per cent aqueous solution of glycol formal.  They are then dipped in an after treatment bath consisting of a 12 per cent solution of glycol diacetate at room temperature. In example 2 glycol diacetate is added to the initial solution and the coagulation bath consists of an aqueous mixture containing 10 per cent of glycol formal and 12 per cent of glycol diacetate, thus dispensing with the after treatment.  The after treatment in the first example and the coagulation in the second example may be carried out continuously.  Specification 587,309 is referred to.

When the knob is turned in the direction in which the pawl slides over the teeth, the curler is rotated to wind the hair thereon, and when rotated in the opposite direction the member 4 is rotated relatively to the member 1 to close the casing, the root of the tress being gripped between strips 5, 6 secured to the edges of the member 1, 4. To hold the member 4 of the casing in the closed position, it is provided with abutments 8, Fig. 3, engaged by cams 7 carried on a shaft 29 rotatably mounted in bearings on the outside of the casing. Passages for the supply of steam and cold air and for the return of the water of condensation are provided in the end of the socket 2, the passages for steam and cold air being alternatively closed by a ported pivoted obturator 19. The passages are connected by flexible tubes 24, 25, 26 passing through the handle 3 to a union member provided with nipples engaging in one of a series of sets of sockets in a distribution board connected to the steam and cold air supplies and to a return pipe for the water of condensation. In order to protect the scalp from injury, the casing is provided with a comb 22, Fig. 3, adapted to engage the root of the tress, the comb being secured to a perforated tube 23 through which cold air is supplied between the comb and the casing.

Abstract: 962,834. Casting machines. E.M.B. CO. Ltd. Feb. 5, 1963 [Feb. 20, 1962], No. 6479/62. Heading B3F. In a hot chamber die casting machine the area of the inlet aperture or apertures 12 of the injection chamber 11 is variable so that the speed of entry of the molten material can be adjusted, so as to prevent material from spilling from the machine before the injection stroke is initiated. The variation in the inlet area may be effected by adjustment of the withdrawn position of the injection plunger 17 so that the apertures 12 are partially covered by the plunger in its withdrawn position. Said adjustment may be effected by adjustment of the stroke of the plunger actuating piston 19 by axial movement of a valve seating 23, or a stop, or by screw-threaded means on the coupling rod 18. In a further modification the inlet area may be varied by an adjustable sleeve which may be cam-operated.

Abstract: 709,622. Sifting apparatus. BROSS, E. March 15, 1950 [Oct. 14, 1948], No, 6550/50. Class 117 [Also in Group V] A porous building element is made by shaking plastic material, e.g. cement mortar, through a screen into a mould, the mass falling into the mould in a granular condition and the individual particles coming to rest in adjacent relation with spaces between the particles. The perforations of the screen are of such a size and are so constructed as not to allow the material to drip through on being poured onto the screen, and the screen, mounted above the mould, is shaken at a frequency which is so high that the material is caused to pass through the screen. The particle size of the material is up to about 5 mm., the width of the mesh of the screen is about 10' mm., and the frequency of vibration may be 9,000 per minute. Fig. 1 shows a screen box 1 mounted above a mould 17 and shaken by devices 13, 14. The screen consists of parts 10, 11, 12, and 15, 16 at different levels. The material falling from the screen may pass through a space which contains a finely-divided binding agent which coats the particles of material. Fig. 2 shows a modified device having tubular feed devices 20, 21 and 22 vibrated by means 18, 19. The screens used in the invention may be of different size or shape, or the perforations may have different cross-sectional shapes in different parts of the screen, or the perforations at different levels may be at different distances apart.

Abstract: 1,219,885. Fatty acid separation. A. KOEBNER. 7 Feb., 1969, No. 6709/69. Heading C2C. [Also in Division C4] In a process for the separation of a mixture of fatty acid esters and rosin acids, this mixture is neutralized by reaction with an alkali-metal or ammonium base in aqueous solution and in the presence of at least one mole (per mole of rosin acid) of an alkali-metal or ammonium aryl or alkylaryl sulphonate (wherein the alkyl group or groups together contain not more than 8 carbon atoms), the thus formed mixture is allowed to stand so that it separates into two layers, the upper being an oily layer consisting of the fatty acid esters, the lower being an aqueous layer containing the alkali-metal or ammonium salts of the rosin acids, and the two layers are then mechanically separated and their constituents recovered. The salt used may be sodium, potassium or ammonium benzene, toluene, cumene, cymene, or xylene sulphonate. The neutralization should be complete, using an exact amount or slight excess of sodium or potassium hydroxide or carborate, preferably at 20-80‹ C. The aqueous rosin-acid salt solution may be acidified with sulphuric acid to recover the rosin acids. The starting material may be tall oil esterified with an insufficient quantity of methyl alcohol, the fatty acids thereby being esterified but not the rosin acids.

Abstract: 678,034. Television. MASTERADIO, Ltd. March 19, 1951 [March 17, 1950], No. 6716/50. Class 40 (iii). [Also in Group XL (c)] In a television receiver, the central portion of the image is magnified by modifying the line saw-tooth current wave-form so that the central range has an increased velocity, and to limit the image distortion thereby introduced the frame wave-form is modified similarly or subjected to an amplitude increase. In the Figures, the deflection coil 1 is driven with a saw-tooth current 7 to which is added suitably phased half sine-wave current 9 derived from resonant circuit 5, 6 via diode 3, the resulting wave-form 11 having an increased rate of scan over the central range 10. The diode 3 also functions as the conventional energy restoring diode, the impulses passing through the diode when the field in the deflector coil collapses, shock exciting the tuned circuit. A switch 13 or 14 is provided to cut out inductor 5 or add extra capacity and so remove the modifying wave-form to allow the scan circuit to operate normally. An additional switch (not shown) controls the height of the frame scan by adding a small amount of negative feedback or by other means. In another embodiment, Fig. 1 (part not shown), the resonant circuit is energized by coupling from the scanning generator or an oscillator tuned to the same frequency.
